The discussion of calibration in the datasheets for the various AD411X products is a bit thin. And I'm getting some confusing results with my attempts on an EVAL-AD4111.
So, for the record, what "Full Scale Range" voltage should I place across the SE and Differential inputs for a System Gain calibration?
Does this change if AVDD is 3.3V versus 5.0 volts?
Does it matter if IOVDD is 3.3V or 5V?
Finally, I'm surprised to see offset voltages of hundreds of microvolts after a system offset calibration. Is this to be expected? Note 2 under the specifications states that "Following a system zero-scale calibration, the offset error is in the order of the noise for the programmed output data rate selected." I'm using the SINC3 filter and a 10SPS data rate which on table 8 is in the range of 20uVp-p.
